teresa repartee un chocolate entre sus hermanos. ella le dio 1/3 a miguel y 1/4 a diego. que parte de chocolate repartido teresa
jekas [21]

Answer:

Teresa tiene 1 chocolate.

Ella le da 1/3 del chocolate a Miguel, entonces ahora Teresa tendrá un chocolate menos un tercio de chocolate, es decir, ella tiene:

1 - 1/3 = 3/3 - 1/3 = 2/3 de un chocolate.

Ahora le da 1/4 a diego, entonces lo que le sobra va a ser:

2/3 - 1/4

recordar que tenemos que tener el mismo denominador en ambas fracciones, entonces podemos reescribir esto como:

(4/4)*(2/3) - (3/3)*(1/4)

(a cada fracción la multiplico y divido por el denominador de la otra)

8/12 - 3/12 = (8 - 3)/12 = 5/12

Es decir, Teresa finalmente tiene 5/12 del chocolate.

Entonces la parte de chocolate que repartió es lo que le falta, que se obtiene como:

1 - 5/12 = 12/12 - 5/12 = 7/12

Ella repartió 7/12 de su chocolate.

For a quadratic equation where: 2++=0
otez555 [7]

Answer:

Solutions will be unreal

Step-by-step explanation:

Given the quadratic equation ax^2+bx+c

The discriminant of the function determines its nature of its root

Discriminant D = b^2-4ac

If D <0, it shows that the roots of the equation will be a complex value. since D is less than 0 and the square root of a negative number does not exist. Hence, the solutions will be unreal

How much water must be evaporated from 130 gallons of a 9% acid solution to make a 12% acid solution?
Bad White [126]

Answer: 33 gallons

Step-by-step explanation:

We initially have 130 gallons of a 9\% acid solution and we need to change it to a 12\% acid solution, and for that it is necessary to evaporate n gallons of water.

So, this situation can be mathemtically expressed as follows:

(130)(9\%)=(130-n)(12\%)

Then:

(130)(\frac{9}{100})=(130-n)(1\frac{12}{100})

Isolating n:

11.7=15.6-0.12 n

n=32.5 \approx 33

Hence, we need to evaporate 33 gallons of water.
